There are many kinds of wirings which are being done in buildings. Electrical Wiring is one of them where a cable tray is used. Cable tray is a system that is used for power transmission as well as distribution and sometimes even used in communication systems. Cable tray is used when changes of wiring are involved because you need a special case or a tray where cables can accumulate easily. And because of its wide uses, you can find many cable tray manufacturers in UAE.

These cable trays are made up of various kinds of materials but Metar as Cable Tray Manufacturers use stainless steel, galvanized steel, glass-fiber reinforced plastic, and sometimes even aluminum. Usually, manufacturers use stainless steel for their manufacturing but as per the situation and conditions, different materials are also used. Galvanized steel tray is made after fabricating and cutting the steel sheet into proper shape. It is then painted with a zinc-rich compound. These trays provide extra protection to the cables which extends the life of these cables. These Cable trays also provide ventilation to enhance the life of cables. The standard length is 2500mm, height can vary from 30mm to 100mm and width can vary from 40mm to 1000mm.

Different types of Cable Trays

There are many cable tray suppliers in the UAE who are renowned to create different types of cable trays for using them under different circumstances. Cable Trays are also manufactured in the same way. There is a cable trough that is used to carry the cables which is also known as a cable channel. The cable trays which are available in the market accordingly are as follows:

  • Light Duty Cable tray, also known as P Type.
  • Medium Duty Cable Tray, also known as M Type.
  • Heavy Duty Cable Tray, also known as R Type.
  • Light Duty Cable Tray or LDT are used for light-duty applications and are easy to install.
  • Medium Duty Cable Tray or MDT is used to provide extra protection and strength to the cable components which improves the lives of these cables.
  • Heavy Duty Cable Tray or HDT is used for extra protection and is installed very easily, and has high accessibility.

Bonn Group is considered to be the best cable trays manufacturer in Dubai that also deals in creating the below mentioned variety of trays.

  • Wrap Over Coupler
  • Bend Coupler
  • Plate Coupler
  • Blind End
  • Fastenings
  • Divider
  • U Coupler
  • Fish Plate and many others.

These cable trays are used as they provide extra protection to the wires and improve their life. These are also used to avoid any discomfort to the cables and prevent them from getting damaged. But these cable trays need regular cleaning as dust particles settle on them easily. So to protect your system and cables, always use cable trays.

FAQs:

General Information

What is a cable tray?

A cable tray is a system used to support insulated electrical cables used for power distribution, control, and communication. It provides a pathway for cables to run across distances within a building or structure.

What are the types of cable trays?

There are several types of cable trays, including:

  • Ladder Cable Trays: Consist of two side rails connected by rungs.
  • Solid Bottom Cable Trays: Have a flat, solid bottom without ventilation.
  • Trough Cable Trays: Have a solid bottom with side rails and ventilation holes.
  • Channel Cable Trays: Enclose the cables completely.
  • Wire Mesh Cable Trays: Made of wire mesh, often used for data cables.
  • Single Rail Cable Trays: Have a single central spine, used in low-load areas.
What materials are cable trays made from?

Cable trays are commonly made from:

  • Steel: Often galvanized for corrosion resistance.
  • Stainless Steel: For high-corrosion environments.
  • Aluminum: Lightweight and corrosion-resistant.
  • Fiber-Reinforced Plastic (FRP): For highly corrosive environments.
What are the benefits of using a cable tray system?
  • Organized Cable Management: Keeps cables organized and easily accessible.
  • Flexibility: Easy to add or remove cables as needed.
  • Support and Protection: Supports cables over long distances and provides physical protection.
  • Ventilation: Allows heat to dissipate, preventing overheating.
How do you choose the right cable tray?

When choosing a cable tray, consider:

  • Load Capacity: The weight of cables it needs to support.
  • Environmental Conditions: Corrosive environments might require special materials.
  • Cable Types: Different trays are better suited for different types of cables.
  • Installation Requirements: Ease of installation and maintenance.
How are cable trays installed?

Installation typically involves:

  • Planning the Route: Determining the path of the tray.
  • Mounting the Tray: Using supports and brackets to mount the tray to walls, ceilings, or floors.
  • Securing the Cables: Laying the cables in the tray and securing them with ties or clamps as needed.
  • Connecting Sections: Ensuring electrical continuity and mechanical strength between tray sections.
What are the load and span considerations for cable trays?
  • Load: The weight of the cables and any additional loads (like dust, ice, etc.) the tray will bear.
  • Span: The distance between supports. Longer spans require stronger trays or additional supports.
What are NEC and NEMA standards for cable trays?
  • NEC (National Electrical Code): Provides guidelines for the installation and use of cable trays in the US.
  • NEMA (National Electrical Manufacturers Association): Sets standards for the design and performance of cable trays.
Can cable trays be used outdoors?

Yes, cable trays can be used outdoors, but it’s important to select trays made from materials that can withstand environmental elements such as UV radiation, moisture, and temperature variations.

How do you maintain a cable tray system?

Maintenance involves:

  • Regular Inspections: Checking for physical damage, corrosion, and proper support.
  • Cleaning: Removing debris that could obstruct ventilation.
  • Tightening Connections: Ensuring all bolts, screws, and clamps are secure.
  • Updating Layouts: As cables are added or removed, ensuring the tray is not overloaded.
What safety considerations should be taken into account with cable trays?
  • Load Limits: Do not exceed the rated load capacity.
  • Grounding: Ensure proper grounding to avoid electrical hazards.
  • Secure Cables: Properly secure cables to prevent them from moving and causing damage.
Can cable trays be used for both power and data cables?

Yes, cable trays can be used for both power and data cables, but it’s crucial to maintain proper separation to avoid interference, following applicable standards and regulations.
